( #3333=superdoc: print w/replies, xml ) Need Help??

I'm desperately trying to get timeouts to work and came up with this test code:

use Sys::SigAction qw( set_sig_handler ); eval { my $h = set_sig_handler( 'ALRM' ,sub { die "TIMEOUT\n"; }, { mask=>[ 'ALRM' ], safe=>1, }); eval { alarm 3; $opened= open my $check, '-|', 'sleep 60'; if ($opened) { # slurp its output $line= do { local $/; <$check>; }; $exit_code= $!+0; $closed= close $check; } alarm 0; }; alarm 0; die $@ if $@; }; alarm 0; print $@;
Of course I can't really ready something from a "sleep" command, But I expected this to return after 3 seconds with a "Timeout". Instead I have to wait 60 seconds, so the full sleep-time.

I also tried a different command than "sleep" like, for example, a long running "find" command but still the sleep does not die.

What am I doing wrong or what do I misunderstand?

    [Discipulus]: yes Eily, thanks oiskuu but i dont get it.. ;=( maybe I'll ask a SOPW
    [LanX]: all combinations with same amount of left and right?
    [Eily]: if you want to store in a structure with the coordinates as key, arrays might do, since the keys are going to be 0..n
    [LanX]: (Pascale path)
    [Eily]: paths like that
    [Discipulus]: yes Eily++ (very keen) I want to integrate my project with a 17th experiments. I want to colorize in sequence all paths
    [oiskuu]: Yeah, modifry the recursive func combinations() to return not the number, but the paths themselves.
    [Eily]: Discipulus I'd do that by starting from the bottom node I think. That way it can inherit the paths from the two nodes above (and so on, recursively)
    [LanX]: oh I meant fixed amount
    [LanX]: every path must have l left and r right edges and l and r are fixed and l+r is the height
